Consensus Summary

What owners say

Aggregated themes from hundreds of discussions across Reddit, Team-BHP, and direct owner reports.

Feature density

Ventilated seats, Bose audio and sunroof in a sub-4m — owners feel they got a segment-above cabin.

Stiff ride

Like the Seltos, the firm low-speed ride over potholes is the most common gripe.

Diesel AT

The only diesel automatic in the class — owners doing long commutes swear by it.

Rear space

Better boot than rivals but rear knee-room is tight for taller families.

The biggest issue is the firm low-speed ride. It gets really annoying in daily usage and makes me regret not looking at other segment options.

The waiting period for the popular variants is ridiculous — dealers are quoting 4 months and forcing you to buy overpriced accessories and insurance from them to get early delivery.

The suspension is tuned too soft. There is a lot of body roll around corners, and the car floats and bounces on wavy highway roads, making rear passengers feel car-sick.

The engine refinement is top-notch and features are great, but the 3-cylinder thrum at lower RPMs is slightly noticeable. Mileage is highly sensitive to throttle inputs (9 to 15 km/l).
